The genome sequence of the Minor Shoulder-knot, Brachylomia viminalis (Fabricius, 1777).

We present a genome assembly from an individual male Brachylomia viminalis (the Minor Shoulder-knot; Arthropoda; Insecta; Lepidoptera; Noctuidae). The genome sequence is 782.2 megabases in span. Most of the assembly is scaffolded into 31 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 16.15 kilobases in length. Gene annotation of this assembly on Ensembl identified 20,191 protein coding genes.
